This patch removes all USE_REQUEUE_PI and __ASSUME_REQUEUE_PI. It is as follow up from BZ#18463. Checked with a build for x86_64-linux-gnu, arm-linux-gnueabhf, m68-linux-gnu, mips64-linux-gnu, and sparc64-linux-gnu. * nptl/pthreadP.h (USE_REQUEUE_PI): Remove ununsed macro. * sysdeps/unix/sysv/linux/arm/kernel-features.h (__ASSUME_REQUEUE_PI): Likewise. * sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_REQUEUE_PI): Likewise. * sysdeps/unix/sysv/linux/m68k/kernel-features.h (__ASSUME_REQUEUE_PI): Likewise. * sysdeps/unix/sysv/linux/mips/kernel-features.h (__ASSUME_REQUEUE_PI): Likewise. * sysdeps/unix/sysv/linux/sparc/kernel-features.h (__ASSUME_REQUEUE_PI): Likewise. --- ChangeLog | 14 ++++++++++++++ nptl/pthreadP.h | 12 ------------ sysdeps/unix/sysv/linux/arm/kernel-features.h | 1 - sysdeps/unix/sysv/linux/kernel-features.h | 5 ----- sysdeps/unix/sysv/linux/m68k/kernel-features.h | 1 - sysdeps/unix/sysv/linux/mips/kernel-features.h | 1 - sysdeps/unix/sysv/linux/sparc/kernel-features.h | 1 - 7 files changed, 14 insertions(+), 21 deletions(-) diff --git a/nptl/pthreadP.h b/nptl/pthreadP.h index 4f76cbb..7fc1e50 100644 --- a/nptl/pthreadP.h +++ b/nptl/pthreadP.h @@ -603,18 +603,6 @@ extern void __wait_lookup_done (void) attribute_hidden; # define PTHREAD_STATIC_FN_REQUIRE(name) __asm (".globl " #name); #endif -/* Test if the mutex is suitable for the FUTEX_WAIT_REQUEUE_PI operation. */ -#if (defined lll_futex_wait_requeue_pi \ - && defined __ASSUME_REQUEUE_PI) -# define USE_REQUEUE_PI(mut) \ - ((mut) && (mut) != (void *) ~0l \ - && (((mut)->__data.__kind \ - & (PTHREAD_MUTEX_PRIO_INHERIT_NP | PTHREAD_MUTEX_ROBUST_NORMAL_NP)) \ - == PTHREAD_MUTEX_PRIO_INHERIT_NP)) -#else -# define USE_REQUEUE_PI(mut) 0 -#endif - /* Returns 0 if POL is a valid scheduling policy. */ static inline int check_sched_policy_attr (int pol) diff --git a/sysdeps/unix/sysv/linux/arm/kernel-features.h b/sysdeps/unix/sysv/linux/arm/kernel-features.h index 4923dfd..e13b049 100644 --- a/sysdeps/unix/sysv/linux/arm/kernel-features.h +++ b/sysdeps/unix/sysv/linux/arm/kernel-features.h @@ -23,7 +23,6 @@ futex_atomic_cmpxchg_inatomic, depending on kernel configuration. */ #if __LINUX_KERNEL_VERSION < 0x030E03 -# undef __ASSUME_REQUEUE_PI # undef __ASSUME_SET_ROBUST_LIST #endif diff --git a/sysdeps/unix/sysv/linux/kernel-features.h b/sysdeps/unix/sysv/linux/kernel-features.h index 318fcf9..e6a2720 100644 --- a/sysdeps/unix/sysv/linux/kernel-features.h +++ b/sysdeps/unix/sysv/linux/kernel-features.h @@ -101,11 +101,6 @@ #define __ASSUME_PREADV 1 #define __ASSUME_PWRITEV 1 -/* Support for FUTEX_*_REQUEUE_PI was added in 2.6.31 (but some - architectures lack futex_atomic_cmpxchg_inatomic in some - configurations). */ -#define __ASSUME_REQUEUE_PI 1 - /* Support for recvmmsg functionality was added in 2.6.33.
